Using SAS PROC SQL, I think I have isolated the baby-booms in the world population file.

I used about five lines of PROC SQL code and was able to isolate the age bands where the older age bands are larger than the smaller age bands. This is the math expression I am using to define a baby-boom. I did this using two identical files. I need to check my results in the output file to make sure I have gotten what I expect.
